e flat, rectangular body of the device "mnieh. is constructed of elongated plates 2 and These plates are of metal, such as or iron, and are disposed coextensive uh each other; being maintained in spaced latfon by the longitudinal spacing land 5 which are interposed between v olates the side edges thereof. The plates 2 and 3 are 'detachably connected by means of the bolt member 6, which extend through the said plates and'the spacing strips, just described. The plates 2 and 3 provided at one end of the body with lateral flanges 7 and 8 respectively, which of the plates outwardly at' ight an i m'BltEtQ. A reinforcing plate 9 is adaptd toiit against the outer faces of the said es and to be secured between the said i and transversely extending head it; by means of the bolt members 11,

This boss opening" is led for the reception .of the inner end ()ffltubular guide n for the chisel, which will be 1oresently is mounted for longireeiorocation. The inner end pr- Ell cilia Eli "tion of th stem is adapted for sliding 1 movement through the head plate opening 18, the 'alining opening 19 provided in the "n oi'cing plate 9 and the longitudinally medial slots- 20 and 21 of the "olates :2 and 3 respectively, the said being disposed in registration with eaeli other and having their longitudinal s concaved transversely concentric With s The inner end Wells 2-2 and 23 OI the slots 26 and 21 respactively are q serve as limiting ta es for onfiat baisel blade is mounted for longias.

way formed between the body 3 with its parallel side edges ictionally enstrips 4,- and 5. The blade 5 is secured mewithin the transverse slot 26 proinner ed e of the diall means of the pin 27, it being understood that this edge of the blade bears s uarely aganist 'the inner wall of the'stem s 0t so that no strain will be sustained by the securing pin 27 during the driving operation of the chisel wh.ich will be described full hereinafter. I The Opposite, outer edge 280 the blade 2?, which extends at right angles to the longitudinal axis of the body 1, is sharpened so The body plates 2 and 3 are provided with alining circular openin 's 29 and 30 of large diamfi ne a mouth throughifiwhiohfi the cutting edge 28 of the chisel. blade is" v eter, which de movable. The said blade is provided medially upon its cutting edge with an outward projection 31 'which has a rounded, sharpened cutting face.

I A strikin head-.32 is provided upon the outer end 0 the chisel stem 18 for engagement by a heavy mallet, or similar operating implement (not shown). In the operation of the device in dehorning cattle, the horn is inserted through the mouth of the instrument provided by the body openings 29 and 30, when .the chisel blade is in the position indicated by the dotted lines in Fig. 1 of the drawing. When the-device has been adusted upon thehorn so that the projection 1 upon the cuttin edge of the chisel enthe body of. the device is held in position by grasping the tubular member 17 as a handle with one hand, and the other hand is used .to strike the head 32 of the operating stem 13 forcibly with a heavy mallet, or the like. The projection 31 of the chisel will penetrate the horn first and then the straight cutting edges thereof will complete the"'cut-' ting operation easily and without danger of crushing or splinteringthe horn, owing to this peculiar construction of cutting edge.

' Should the animal become fractions and endeavor to resist the operation, no harm could result to the animal nor to the'dehorning imlement, owing to the manner in which the atter is applied to the ho'r'n, as permitted by the construction of the bod of the device and the arrangement 0 the chisel therein,

What is claimed is:

1. A device of the class described comprising a body having an opening therein cefining amouth, a cutting element movably mounted within the said. body and-beiug adapted to traverse the said mouth, the

said cutting element being in the form of a flat blade havinga transversely extend ing, straight cutting edgef'and a medial plates 2 and in the inner end of the stem 18 by- :its inner endwith the said of the said stein.

feral openings alining with one plate secured projection formed upon the said outtin edge, the said projection being rounde transversely and sharpened to formacutting edge disposed in the plane of the main cutting edge,

2. A device of the class. described comprising a body having a guide slot therein and a lateral opening in communication therewith tov define .a inouth,a chisel blade slidably mounted within the said slot and j haviugya cutting edge, a tubular uide j -memberronnected with the said bo in communication with its guide slot, an an stem slidably. mounted within the member and being connected at lade.

3. A. device of the class described comoperating saidgui uprising a body havinga guide slot therein and a lateral opening in communication therewith to define a'mouth, a chisel blade Sl1dlbly= mounted within thesaid slot and having a. cuttin' edge, a tubular 'de member coii necte with the said b015 in communication with its guide slot, an-o crating stein slidably mounted within the said guidemember and being connected at its 1i iner' end with the said blade, and a striking head formed upon the outer end i. A device of the class described compr1s1ng an elongated body including a pair of relativelyspace'd, coextensive plates, and a pair. of spacingstrips interposed between said plates at the side edges of the same, the edges of said plates at one end bent laterally to rovide of the body bein oppositely extending flanges, a hea late secured detachably to the outer faces-o the said flanges, and being; provided medially .of the saidslots, and a chisel blade connected with the inner end of said stem and plates of the body.

5. A deviceof-the class described comprising an elongated body including a pair,

of relatively spaced,coextensive plates, and
